<font face="Verdana">Oh, have no fear... I blast through them
regularly on HF! ;-) At those frequencies they are basically
transparent.<br>
<br>
However, the story is different at microwave frequencies. The
same principal that makes your microwave oven work are what causes
leaves (mostly the water in the leaves) to absorb microwave
energy. My minuscule knowledge of the ARDEN project is that they
use repurposed WiFi routers in the 2.4 or 5Ghz ranges.<br>

<pre>Hello Bars,
Has anyone set up Arden or a mesh network as a local wireless net through ham radio? Arden stands for "Amateur Radio Emergency Data Network". It's a way to have a wide range personal data network among hams to use in case of emergencies. I'd like to see how much interest there is in the club to make this a club project and build them together. The hardware is low power and relatively inexpensive. I'm sure we have some expertise in the club who can speak much better on it than I. Let me know what you think.
